6 / 16 page 1996 Feb 01 6 Philips Semiconductors Product specification Triple RGB 6-bit video analog-to-digital interface TDA8707 HANDLING Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is desirable to take normal precautions appropriate to handling integrated circuits. CHARACTERISTICS (see Tables 1 and 2) VDDA =VDDD = 4.5 to 5.5 V; VSSA and VSSD short-circuited together; VDDA − VDDD = −0.5 to +0.5 V; Tamb = −40 to +85 °C; SLT=0V; CREFH = 2 V, CREFL = 0.5 V, CL = 15 pF; typical values measured at VDDA =VDDD =5V; VSSA =VSSD = 0 V and Tamb =25 °C; unless otherwise specified.
